Cannot drag and split tabs in a wx.lib.agw.aui.auinotebook with wx 3.0.0.0

When I try to drag a tab into wx.lib.agw.aui.AuiNotebook so that the wx.lib.agw.aui.AuiNotebookwill be split in 2, I get this error:
wx._core.PyAssertionError: C++ assertion “!wxMouseCapture::IsInCaptureStack(this)” failed at …\src\common\wincmn.cpp(3271) in wxWindowBase::CaptureMouse(): Recapturing the mouse in the same window?

However, when I run my application in another computer, I can drag tabs and notebook can be split into 2.

The problematic PC uses windows 7 and wx 3.0.0.0

The other pc uses windows 7 and wx 2.9.5.0

so does wx 3.0.0.0 have a bug when splitting a wx.lib.agw.aui.AuiNotebook?

Yeah sorta. Not sure how it will be dealt with but here is info on how to fix it until things get sorted out later down the road.
Andrea filed a bug report on this also on the trac also.
See this mail for more info.
